LOOM-SHUTTLE CHECK.

SPECIFICATION formingpart of Letters Patent No. 763,107, dated June 21, 1904. i Application filed February 20, 1904. Serial No. 194,465. (No model.)

Q To au whom t may concern.:

Beit known that 1', BENJAMIN F. McGUINuss, a citizen of the United States, residing at Vorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Loom-Shuttle Checks, of which the following is a speciiication.

My invention relates to looms, and particularly to a shuttle-check for the shuttle-box of a loom; and the object of my invention is to lprovide an improved shuttle-check, or more particularly a supplemental mechanism, combined with the ordinary shuttle-binder and binder-finger to operate the binder-linger and put a greater pressure on they binder to check the shuttles momentum after it enters the shuttle-box and prevent it from being accidentally moved out of the box.

My invention consists in certain novel features of construction of my improvements, as will bc hereinafter fully described.

I have shown in the drawings one end of a lay and one stationary shuttle-box thereon provided with an ordinary binder and binderlinger, withmy improvements combined therewith, suiicient to enable those skilled in the art to understand the construction andkoperation thereof. v

Referring to the drawings, Figure 1 is a top or plan view of a shuttle-box and the end of the lay and a picker-stick with my improvements combined therewith looking in the direction of arrow a, Fig.2. Fig. 2 is afront view of the parts shown in Fig. 1 looking in the direction of arrow I), sameiigure. The shuttle is not shown in this figure; and Fig. 3 is a ver- -tical cross-section on line 3 3, Fig. 2, looking in the direction of arrow c, same figure.

In thev accompanying drawings, 1 is the end of the lay, on the upper side of which is attached the stationary shuttle-box 2.

3 is the shuttle, which passes into the box 2 through the open end in the usual way.

4 is the shuttle-binder, pivotally attached at one end to an upright stud 5 and bent to bear against the shuttle, with its free end extending out from the shuttle-'box and bearing lagainst the pin 6, as shown in Fig. 1, tor act as a shuttle-binder inthe usual way. The picker-stick 7 carries at its upper end the picker 8 to engage the outer end of the shuttle land throw it across the lay when the pickerstick is operated in the usual way.

All of the above-mentioned parts may be of the ordinary and well-known construction and operation.

I will now describe my improvements.

, Ona pin 9, mounted in the casting 10 at the end of the lay, is supported a pivoted lever 11, which extends-up withinv the casting 10 in line with and in the path of, the picker-stick 7. (See Fig. 2.) The lever 11 has preferably a cushion-surface 11', of leather or other suitable material, to engage the rear end of the picker-stick 7. The lever 11 has in this instance a recess 11l on its rear edge, (see Fig.

els or slides on an inclined surface 1,5' on the lower bent end of an arm 15,`extending down from the hub 16 of the binder-finger 16, the upper end of which engages the free end of the binder 4 in ythe usual way. (See Fig. 3.) Said arm may in effect constitute a part of the binder-finger.

Extending directly over the roll 14 and over the inclined end 15 of the arm 15 is a plate 17, secured to the lower side of the lay 1. The plate 17 vhas on its lowersurface astraight flat portion to be engaged by the upper side of the roll 14, as shown in Fig. 2.

Extending down from the longitudinal moving rod 12 is a projection 12, to which is pivoted one end of a rod 18. The other end of said rod 18 is adjustably connected bya turnbuckle 19 with a rod 20, which is pivotally attached to an arm on a corresponding longitudinal moving rod 12, connected with a l `those skilled in the art.

pivoted lever corresponding to 11 in the path or' the picker-stick on the opposite side of the loom. (Not shown.)

rlhe operation of my improvements from the above description, in connection with the drawings, will be readily understood by those skilled in the art.

As the shuttle is thrown across the lay from the opposite side of the loom into the box shown in the drawings it will engage the picker-stick and move the picker-stick backward, or away from the loom. The backward movement of the picker-stick 7 will also move backward the lever11, and with it move the rod 12, away from the loom and cause the roll 14 to ride up on the inclined end V15 of the arm 15 and under the plate 17, to cause the downward motion of the arm 15 and the inward motion of the binder-linger 16 to press the binder 4 against the shuttle, and thus produce a check to hold the shuttle in the box.

Whenthe shuttle is thrown from the shuttlc-box shown in the drawings by the forward movement of the picker-stick, the lever 11 is free to move forward, as shown by dotted lines, and the roll 14 to travel down on the incline 15' to free the binder-finger 16.

The engagement of the shuttle with the lever 11 on the other side of the loom will, through intermediate connections, move the rod 12 and lever 1l shown in the drawing.

The advantages of my improvements in shuttle-check will be readily appreciated by They are of very simple construction and can be readily applied to'looms having shuttle-boxes of ordinary construction.

It will be understood that the details of construction .of my improvements may be varied, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a shuttle check mechanism, the combination with the shuttle-binder, picker-stick,

a lever extending in the path of the backward movement of said picker-stick, and adapted to be engaged thereby, ot a longitudinallymovable rod connected to said lever and means operable by said rod and having sliding engagement with the binder-finger, to positively move inwardly saidv binder-linger on the backward movement of said lever, and said bindernger, substantially as shown and described.

2. In a shuttle check mechanism the combination with the binder-finger, a shuttlebinder and the picker stick, of mechanism intermediate the picker-stick and the bindernger, and in sliding engagement with the latter to positively move inwardly the binderlinger to apply pressure to the binder, when the picker-stick has reached its backward position, substantially as shown and described.

3. In a shuttle check mechanism, the combination With the picker-stick, the shuttlebinder and the shuttle binder-linger, of a lever in the path of and adapted to be engaged by the picker-stick on its backward movement, connections from said lever to the binder-finger, including a part slidable upon the binder-finger to positively move said finger inwardly, to actuate the binder on the backward movement of the picker-stick, and to release said binder on the forward movement of said stick, substantially as shown and described.

4. In a shuttle check mechanism, the combination of a picker-stick, a shuttle-binder, a binder-finger, a part operatively connected therewith and having an incline, mechanism intermediate the picker-stick and binder-linger and having a part movable upon said incline to positively move inwardly the binderinger to apply pressure tothe binder as the picker-stick moves to its backward position.
